Newsletter for Tuesday 15 October

TODAY IN SCIENCE HISTORY NEWSLETTER - 15 OCTOBER

Feature for Today

On 15 Oct 1990, the first arrival of killer bees in the U.S. was recorded in Hidalgo, as the dangerous insects spread up from Mexico into the southern tip of Texas. The killer bees earned their nickname in the media from their more intense defensive swarming behaviour than shown by native bees. Africanized honey bees, better known as killer bees, originated from the cross-breeding of tropical African bees imported a South American country for experimental work. Since the 1950s, the killer bees extended their range northward through Central America. Three years later, on 18 Jun 1993, killer bees were recorded as having spread into Arizona. An article on the Arrival of Africanized Honey Bees in Arizona gives more details on the spread of the AHBs, their effects and the first human fatalities.

Book of the Day

On 15 Oct 1930, Herbert H. Dow died, founder of the Dow Chemical Company, a pioneer the modern American chemical industry. Today's Science Store pick is: Herbert H. Dow,: Pioneer in creative chemistry,, by Murray Campbell who describes Dow's contribution to the development of industrial chemistry, with ample quotations from letters, diaries, notebooks and company records. Lessons learned by Dow as he progressed from the lab were the problems of scalability: concocting something in a beaker would be followed by unpleasant surprises as it would be totally different to put it together on a larger, commercial scale. It is available New from $29.99. Used from $0.52. (As of time of writing.). For picks from earlier newsletters, see the Today in Science History Science Store home page.

Quotations for Today
	A good many times I have been present at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and have asked the company how many of them could describe the Second Law of Thermodynamics. The response was cold: it was also negative. Yet I was asking something which is about the scientific equivalent of: Have you read a work of Shakespeare's? - Baron C.P. Snow, English physicist, novelist and government administrator (born 15 Oct 1905).
	The genes are the atoms of heredity. - Seymour Benzer, American molecular biologist (born 15 Oct 1921).
	If the fit between South America and Africa is not genetic, surely it is a device of Satan for our frustration. - Chester R. Longwell, American geologist (born 15 Oct 1887).

Events
	On 15 Oct of a certain year, the arrival of killer bees was first observed in the U.S. after they had been spreading via Mexico from Central and South America into Texas.
